Earth Observation Data as Public Goods: INPE’s experience Leila Fonseca National Institute for Space Research Brazil
2
Earth observation satellites provide key information about global land change EO data benefits to everyone Images are public goods!
3
Projects as examples of public goods... CBERS program Deforestation assessment in the Amazon Forest (PRODES) Real Time Deforestation Detection (DETER)
4
CBERS Program: China-Brazil Earth Resources Satellite (http://www.cbers.inpe.br) Objectives Build a family of remote sensing satellites to support the needs of users in earth resources applications Improve the industrial capabilities of space technology in Brazil and China
5
CBERS-2B Sensor Configuration mm 0.42.50.71.10.90.51.51.72.3 WFI 260 m (890 km) CCD 20 m (120 km) Built by ChinaBuilt by Brazil PAN 2.5 m (27 km)
6
CBERS 3 – 4 Sensor Configuration mm 0.42.30.71.10.90.51.51.7 2.1 WFI 73 m (860 km) MSS 40 m (120 km) CCD 20 m (120 km) MUX 10 m (60 km) PAN 5 m (60 km) Built by ChinaBuilt by Brazil
7
Policy for CBERS International Data Images acquired by Brazilian station are free (catalogue) (www.dgi.inpe.br/CDSR) Brasil and latin america countries zero-cost fee for direct downlink in existing ground stations Africa will receive images by direct downlink soon Ground station operators are encouraged to distribute CBERS data free of charge on the Web
8
CBERS data distributed in the internet
9
Number of full CCD scenes distributed (145 Mb/scene) 360,000 Number of institutions and companies14,500 CBERS Image Distribution in Brazil (05/2004- 08/2007)
10
What do the private companies say about free CBERS data? Enables new business development Facilitates trial uses for new clients Planning new applications becomes easier Creates jobs by reducing cost of data buys Increases quality by adding data previously unavailable
11
Deforestation Assessment Programs Dalton M. Valeriano
12
Deforestation assessment in the Amazon Forest ( Supports policy- making) year
13
Data available in the Internet since 2003: Methods Tables Maps: Landsat Scene State mosaics Region mosaic Deforestation assessment in the Amazon Forest (http://www.obt.inpe.br/prodes/index.html)
14
Moderate Resolution based Real Time Deforestation Detection – DETER (http://www.obt.inpe.br/deter/) TERRA MODIS - Moderate-resolution Imaging Spectroradiometer Observation period: 3 dias Spatial Resolution: 250 m CBERS - China-Brazil Earth Resources Satellite WFI – wide Field Imager Observation period: 5 dias Spatial Resolution: 260 m Alarm system: detect new deforestation areas Supports law-enforcement
15
Cuiabá Receiving Station Latest cloud-free MODIS Previous deforestation assessment DETER: Data and Information Flow Data processing in INPE Partial results to IBAMA and integration in the internet Analysis and distribution to enforcement agents by IBAMA
16
Modis data (may 2004)
17
Modis data (june 2004)
18
CBERS CCD data (July 2004)
19
Check in the field...
20
DETER Features and Products
21
New deforestations
22
Data obtained in the web can be used in any GIS
23
Query to Fire Detection Database Altamira/PA
24
What can we achieve? There is an enormous demand for remote sensing data in the world Free on-line data access will significantly increase the number of users of earth observation data Free data will lead to a much better understanding of the global Earth System
25
Will the Global Earth Observation System of Systems be based on free and open data policies?
